123°Step-by-step explanation:
It is assumed GE and DA are parallel
EFH and FCA are same side interior angles and therefore supplementary
m∠EFH + m∠FCA = 180On the other hand, ∠HBA is exterior angle of triangle CHB, so it is
m∠HBA = m∠FCA + m∠CFB143 = m∠FCA + 90m∠FCA = 147 - 90m∠FCA = 57Now, find the value of m∠EFH

balls of wool
1 yard = 3 feet
900 yards x 3 = 2,700 feet needed
subtract what she has:
2700-200 = 2,500 feet more needed
2,500 / 500 = 5 balls needed

The product of the given expression is -3ed + 3e^2 showing that they contain two terms and the product has a degree of 2.
How to find the product of expressions?
Equations are expressions separated by an equal sign.
Given the following expression
(–d + e)(4e + d).
We are to take the product of both expressions.
Expand to have:
(–d + e)(4e + d) = -4ed - d^2 + 4e^2 + de
(–d + e)(4e + d) = -3ed + 3e^2
Hence, there are two terms in the solution and the product is degree 2.

ABC ~ DEF. What sequence of transformations will move ABC onto DEF?
The transformation that is implemented is clockwise rotation by 270° about the origin and dilation by a scale factor of 1/2 .
The process of transformation an existing graph or equation into a new graph is known as graph transformation . The alteration of algebraic equations is a typical form of algebraic challenge.
A transformation modifies the graph of a parent function. Dilations, reflections, and translations are the three distinct types of transformation . The y-values of a function can be changed vertically, or the x-values can be changed horizontally (affects the x-values).
In the given figure we can see that the length of the side BC of the figure is 4 units, where as the length of the corresponding side in the image is
2 units . Hence the image is dilated buy a scale factor of 1/2 .
And from the transformation figure it is clear that the image has rotated either 270° clockwise or 90 ° counterclockwise.
Hence the second option on transformation is correct.

Step-by-step explanation:
5. If your father earns Rs. 40,000/-, mother earns Rs. 35,000/- and your brother earns Rs. 25,000/- per month and your friend's father earns Rs. 45,000/-, mother Rs.30,000/- and brother earns Rs. 15,000/- then whose monthly income is more and by what percent.
Answer:
✏The correct option is B Rs 73,333
Per capita income is the sum of all income sources, divided by the total number of people. Here the gross income of the family is = Rs (1,80,000+ 40,000) = Rs 2,20,000, the pocket money won't be added as it is an expense for the family. Then the per capita income of the family= Gross income / 3 (as the family has three members) = Rs 73,333.
Step-by-step explanation:
Percent is a relative quantity. Earning of our family is more than our friend's family (on monthly basis), by 11.11% approximately. (compared to friend's family's monthly income)
How to find how much percent 'a' is of 'b'?Percent is a relative quantity, as it is the measure of one quantity per 100 units of other quantity.
Suppose a number is 'a'Suppose another number is 'b'We want to know how much percent of 'b' is 'a'.
Then, it is calculated as:
[tex]\dfrac{a}{b} \times 100[/tex]
(in percentage)
For this case, we're specified that:
For our family:
Income of father = ₹ 40,000Income of mother = ₹ 35,000Income of brother = ₹ 25,000Total monthly income = ₹(40000 + 35000 + 25000) = ₹100,000
For friend's family:
Income of father = ₹ 45,000Income of mother = ₹ 30,000Income of brother = ₹ 15,000Total monthly income = ₹(45000 + 30000 + 15000) = ₹90,000
Thus, we see that friend's family's monthly is monthly ₹10,000 less than our family's monthly income.
We need to find how much percent this ₹10,000 is of their family because we need to find by how much percent our family's income is more than the friend's family's monthly income (so comparison is with respect to the monthly income of friend's family).
Let P be the percent the ₹10,000 is of the amount ₹90,000
Then, we get:
[tex]P = \dfrac{10000}{90000} \times 100 = \dfrac{100}{9} \approx 11.11 \%[/tex]
Thus, earning of our family is more than our friend's family (on monthly basis), by 11.11% approximately. (compared to friend's family's monthly income)

The mnemonic SOH CAH TOA is intended to remind you of the relationship between side lengths and trig functions in a right triangle. It tells you ...
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse

QR is the side opposite angle P. PR is the side adjacent to angle P. PQ is the hypotenuse of this triangle. Translated to the given triangle, the trig functions are ...
